METHOD OF MAKING PAPE R BOXES.

SPECIFICATION forming part of Letters Patent No. 521,031, dated June 5,1894.

Application filed October 12, 1893.

To aZZ whom it may concern.-

Be it known that I, ALBERT C, LUTZ, a citizen of the United States,residing at the city of Cleveland, county of Ouyahoga, and State Methodof Making Cylindrical Paper Boxes, of which the following is aspecification.

This invention relates to a new method of making cylindrical paperboxes, having for its object to greatly facilitate and expedite suchwork, and consists in the means and method employed substantially ashereinafter described and pointed out in the claim.

In the accompanying drawings Figure 1 represents a grooved roller uponwhich the cylinders are formed. Fig. 2 represents the same having acylinder formed thereon.

In carrying out my method, I provide a two oppositely locatedlongitudinal grooves A A. Next I take sheets of paper or strawboard B,and insert one edge of a sheet in one of the grooves, bending the paperor board down to form a flange, then rolling the paper or board oncearound the roller, then I paste or size the balance of the surface ofthe paper orboard, and then continue to roll the same until the wholesheet has been rolled up, then lay aside the roller with the paper orboard thus rolled thereon to dry. When they have become sufficientlydriedgl next, with a sharp knife cut a longitudinal slit in the papercylinder, by carrying the knife along in the groove opposite to thegroove having the flanged edge of the paper inserted, with sufficientforce to sever the paper cylinder. I

erial No 488,001. (No model.)

next take a strip of cloth or tape G,gumn1ed or pasted and apply thesame over the said slit in. the cylinder for the purpose of making ahinge, when this has become sufficiently dried,I next cut a slit alongthe paper cylinder on the opposite side to the hinge, by carrying theknife in like manner for cutting the other slit, taking care howevernot-to cut off the flange, but carry the knife along the side of it soas to leave the flange on the edge of the half cylinder. These cylindersI then out into required lengths for boxes, and put heads in ends ofthese blanks to complete the boxes, which may be finished off in anysuitable manner.

Having described my invention, I claim- The method herein described formaking paper boxes, which consists first in providing a grooved roller,next inserting the edge of the paper or board in one of the grooves insaid roller, then bending down the paper or board, next pasting orsizing the paper and rolling up the balance of paper on the roller, nextwhen dried cutting a slit in the paper cylinder and gumming over theslit a strip of cloth or tape to form a hinge, next cutting slip on theopposite side of the cylinder, then cutting said cylinders into suitablelengths for boxes, and attaching the heads substanpiallg in the mannerand for the purpose set ort .
